ABSTRACT:
Indicator inks, indicators formed by printing or otherwise utilizing the inks and host products utilizing the indicators are disclosed. Reactivity-enhancing adjuvants stimulate enhanced thermal reactivity of diacetylenic or other indicator agents capable of responding to ambient thermal conditions with a visual change signaling an end point. The diacetylenic or other agents may be sensitive or relatively insensitive to ambient temperatures. Use of a reactivity-enhancing adjuvant provides a useful means for adapting the reactivities of indicator agents to the response characteristics of prospective host products, for example perishables such as vaccines or fresh fish and maturables such as fruit, cheese and wine. Some exemplary adjuvants include low-temperature polymerization initiators, for example methyl ethyl ketone peroxide and polymerization accelerators, for example cobalt compounds. Such initiators and accelerators can also be used in combination.
